JACOB J. SOUDER. OF WASHINGTON, DISTRICT OF COLUMBIA.

HEADLESS AND THREADLESS BOLT.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed February 11, 1908. Serial No. 415,315.

To-cll whom it may concern:

Be it known that I, JAcoB J. SOUDER, a citizen of the United States, residing at Washington, in the-District oi Columbia, have invented certain new and'useful Imrovements in Headless and 'lhreadless olts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

My invention relates primarily to bolts, has special reference to that class of bolts which are devoid of screw-threads for connection with a like threadloss meinber.

The invention has for its object a bolt which is headless and threadless, and which is secured in position without the use of screw-threads 1n the wall oi" the retaining member, as shown in l ietters-latentof. the United States, granted to me November 27th, ,1906 No. 836 786, and Novembertime required in applying the bolts.

The invention consists in certain improve-- ments in construction, which Wlll be iully disclosed in the following specification and claims.

In the accompanying drawings, which form-part of this specification:-Figure '1 represents a side and an end view of my improved bolt. Fig. 2 a horizontal section .of a railroad rail-joint, showing a bolt in the openings of the joint and a key inserted between the separated members ofthe bolt at both ends thereofibefore the ends of said members have been bent inward over the keys. Fig. 3 a like vieW' showing the ends of the bolt bent over and inclosing or covering' the outer ends of the keys. Fi 4 a vertical transverse section of a rai -joint showing a bolt in position. Fig, 5 a side elevation of part of a rail-joint showing one of the holes or openings filled by a bolt and key and the other hole open. Fig. 6 a side the manufacture of bolts, by--- view-of a key on a enlarged scale, and Fig. 7 an end view of th same.

Reference being bad to the drawings finely. the designating characters thereon, the numeral 1 indicates a bolt, made in two parts, of merchantable roiled iron, preferably liall round in transverse section, cut to proper length of the bolt required, assembled y placing one piece upon another with their flat sides 2 2, adjacent and normally. in engagement tinioughout their length and secured togelher between the ends of the bolt to prevent lateral displacen'ient by a band 3, of metal, such as a. piece of tubing, or by any other suitable means, such as asection of coiled wire or the like, which will engage the two parts of the belt. Thebolt thus c .)nstructod, presents two unwelded members in parallel planes normally in engagement with each other, and in which the longitudinal libers of the metal are separated in the transverse center of the bolt from one end to the other, and the members of the bolt are separable at both ends thereof.

4, indicates a key or wedge, preferably made of malleable cast iron. The parts-to be secured together, having been properly assembled, the bolt is inserted through the holes provided for the purpose, when the ends of the bolt are-separated, the key t in- 7 sorted between the members 5, 5, the key driven in and properly seated, andthe members 5, 5, bent inward over and upon the key, by the use of a suitable swaging tool or implement for the purpose, applied simult'aneously to both ends of the bolt.

The parts 5, 5, of the members 1, 1, of the bolt are separated or spread by the key 4, so thatthey bear against the inclined walls 8, '8 ol the openings 6 in the fish-plates 7 and the walls 'l'orm seats or bearings for that portion 9-, 9 of the members '1, 1, which engage said walls, and afford resistanceto the pressure exerted by the swaging-tool in bending and swagingthe members 5, 5, at the extremities oi the bolt.v This fish plate 7 reqkuires no change, and one is a duplicate of t 10 other.

- The key 4 isprel'erably provided with a head extending beyond the edges of the wedge and forming shoulders 10, 10, which rest upon the plates 7 While the body 11 of the key is of a width equal to the diameter of.the openings '6 taken at a right angle to the elongation of the opening, orthe in- 0
